`.application med october Y1, 1924. serial No. 741,019.,

To all tof/om it may concern.'y

Be it known that I, ALBERT V. Massin, a

citizen of theUnitedV States, and a resident of the city of New York,Jackson Heights,

boroughof Queens, in the county of Queens and State of New York, haveinvented a new and yImproved Auto Horn, of which the following isa full,clear, and exact'description'.` t l ,This -invention relates to hornsand more particularly to a mechanically 4operated horn which isyespecially adapted for-use on automobiles or the like, an objectof. thein vention being to provide a horn which is not liable to Vget out oforder, which can be easily operated andfwhichwillgive the desired sound.

The great majority of horns of this type in generaluse`r areelectrically operated, and it frequently happens through short circuit--ing and the like the'hornbecomes useless. This is a serious matter to adriver ofan automobile, and Ait is ythe purpose of my in- 'f vention toprovide a horn which vwill be entirely mechanical,l whichv can bemanufactured and sold at a freasonablylow` price, and which will be mostefiicientk in the performance of its functions.

kYVith these and other objects in view, the,

invention consists in certain novel features of construction' andcombinations andar- .rangements of parts whlch w1ll be more fullyhereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view `partly in longitudinalsection and artly in elevation illustrating my improved) form;

Figure 2 is a view in section on the staggered line 2-2 of Figure 1; e

Figure 3 is a view in transverse section on the line 3--3 of Figure 1; n

Figure 4 is a face view of the diaphragm 4. 1 represents a relativelyheavy plate which is circular in form and somewhat cupped, and to theouter edge of this plate a second plate 2 is secured and supports anamplifier 3. This amplifier is secured in a central opening in plate 2and the plates 1 and 2r constitute a circular chamber in` which adiaphragm 4 is'seoured between the edges of the plates. Plate 1 has acentral bearing 5 for a sho shaft 6 on which a circular head 7 is fixedand klocated within the chamber formed bed tween plates 1 and 2, 'Thishead has an anf 13 on shaft 6 so as to impart 'and at its other end tothe shaft nular series of serrations Seach adapted to engage studs 9fixed to the diaphragm so that when the head is revolved it will causethe diaphragm tovibrate and sounds to be emitted through the amplifier3. My invention resides more specifically in .mechanism for operatingthe shaft 6 `andhead 7 there on, which mechanism will now be describedin detail.

Aframe 10 is fixed kto ports three parallel shafts spectively. largebevel gear wheel 29 is fixed and this gear wheel 29 meshes lwith a bevelpinion rotary kmotion to the head 7 when ythe bevel gear 'wheel 29 isturned... This gear wheel 29' is ymade relatively heavy so ythat it hassomewhat the 4plate 1 and sup- 11, 12 and 13, re-

lfunction of a fiy `wheel to` utilize the momentum which may be impartedthereto. VA removable casingy 14 is secured to the frame 10 and isprovided with a longitudinal slot'16 through which a handle 17 projects.The handle 17 is pivotally supported upon a screw or other suitablepivot 1S connected to frame 10, andis formed at its inner end with anintegralv segmental gear 19 which meshes with shaft 12. c

Onthis shaft 12 a convolute spring 21 is Wound and is fixed at one endto this shaft 13. A gear wheel 22 is fixed to shaft 12 and meshes with apinion 23 on shaft 13. This shaft r13 also carries a gear wheel 24 whichmeshes with a gear wheel 25 loose on shaft 11. A second irectly with thegear wheel 22. A ratchet wheel 27 is fixed to the shaft 10 between thegear wheels 25 and 26, and said gear wheels 25 and 26 carry springpressed pawls 28 which engage the ratchet wheel 27. It will be notedthatthe pawls 28 of the respective gear wheels 25 and 26 are oppositelydislgear wheel 26 also loose on shaft 11 meshes posed, it beingdesirable always to turn the 21 thereon. At the same time the gear wheel22 transmits motion through the pinion 23, shaft 1 3 and gear wheel 24to the gear wheel 266. Asthis gear wheel 25is turned its pawl On theshaft 11 va relativelyv a pinion 20 fixed to the t Portion )of the 28Will engage the ratchet Wheel 2T and impart motion to the shaft 11 andthe large bevel gear wheel 29, and the latter will turn the pinion 14and head 7 to sound the horn. W'hen the handle is released the spring 21Will notronly return the handle to its for- Ward position but by reasonof the fact that it directly engages the gear Wheel 26 it will impartYmotionto the ratchet YWheel 2T and shaft 11 to continue the turning,movementY g 4 in the of the gear Wheel 12 and tliehead Same directionas above described ln other Words, the backward and forward movement ofthe handle ldue to the fact that the spring 21 is Wound in onedirectionimparts motion in the other direction will compel the gear Wheel 29 toturn in the same direcv, tion on both movements of the handle.

Various .sight Changes and alterations might be made in the general formof 'theY partsy described Without departing from my invention, and'henceI do not limit myselfA to the preciserdetails set Iforth but considermyself at liberty to l make such slight changes and alterations asfairly fall within the .Selrlf and scope` of the appended claims- Iclaim:

1. A mechanically operated'horn, comprising a diaphragm casing, anamplifier communicating therewith, a rotary head in the diaphragmcasing, having a serrated edge, a stud on the diaphragm engaging theserrated edge of the head, a pinion fixed to turn with the head, arelatively large gear meshing with the pinion, a pivotally mountedlever, a gear train operatively connecting the lever with .the saidgea-r Wheel` a spring Wound by the movement of 'the lever in vonedirection, anda geantrain operated by the spring as the latter'uniyindsto impart a rotary motion to ysaid gear Wheel.

2. A` mechanically operated horn` comprising a Vdiaphragm casing, anamplifier' i communicating therewith, a rotaryv headV in the diaphragmcasing, having a serrated edge, a stud on the diaphragm engaging. theserrated edge of the head, Aa pinion'iixed to turn'ivith the head, arelatively large gear meshing xvith the pinion,`a shaft to which saidgear Wheel Yis connected, a pair of gears looseo'n'the said shaft,pavvls carried by said last-mentioned gears and engaged by the pawls, apivoted lever, a segment fixed'to the lever, a second shaft, a pinion onthe secondV shaft engaged "by the segment. a spring on the second shaft,a gear train connecting the second shaft with one of the pawl carryinggear Wheels, and a gear Wheel fixed to, the second mentioned shaft andmeshing directly with 'the other Vof said pawl carrying-gear Wheels,
